Abstract
The invention relates to an optical recording medium comprising a substrate and a recording layer, wherein the recording layer comprises a complex of formula (I), or, wherein Q2 is a ligand of formula (II), or a tautomer thereof, and R1, R2, R3, R4, R5, R6, R7, and R8 are each independently of the others H, halogen, cyano, COOR9, CONHR9, CONR9R10, R9, OR9, SR9, NHR9 or NR9R10, wherein R9 and R10 are each independently of the other C6-C10aryl, C4-C9heteroaryl or linear or branched C1-C24alkyl, C3-C24cycloalkyl, C2-C24alkenyl, C3-C24cycloalkenyl, C2-C24alkynyl, C1-C12heterocycloalkyl, C1-C12heterocycloalkenyl, C7-C24aralkenyl or C7-C24aralkyl, each of which may be unsubstituted or substituted, it also being possible for R1 and R2, R3 and R4, R5 and R6, and R7 and R8, independently of one another, to be bonded by a direct bond or via a bridge O or S, Mm+ is a transition metal cation having 5 or 6 electrons in the outermost occupied d-shell, L1 is a ligand having a sub-structure N-C, P-C or As-C, L2, independently of L1, is a further ligand containing at least one hetero atom N, P, As, O, S, Se or Te, L3- is CN-, SCN-, NCS-, OCN-, NCO-, N3-, L1-O-, L1-S-, L1-CO2-, L1-S03- or L1-P03-, L4-, independently of L3-, is CN-, SCN-, NCS-, OCN-, NCO-, N3-, L3-O-, L3-S-, L3-CO2- L3-SO3- or L3-PO3-, p and q are each independently of the other a number 0 or 1 (formula III), are each a counter-ion, m is a number 1, 2, 3 or 4 equal to the positive charge in Mm+ and n is a number -2, -1, +1 or +2, so that the quotient (formula IV) is not negative. Amorphous solid layers having excellent optical properties are obtained.
